PURPOSE: The purpose of this study was to investigate the influences of depression, stress, and self-efficacy on the addiction to cell phone use among university students. METHODS: Data were collected through questionnaires from 563 students and analyzed by applying descriptive statistics, t-test, chi-square test, and stepwise multiple regression with SPSS/WIN 16.0. RESULTS: The proportion of depressed subjects was 52.6%. The addictive group scored higher than the non-addictive group in depression rate and stress, but scored lower in self-efficacy. Out of the subjects, 32.9% were found to be addictive users, 31.3% at potential risk, and 1.6% at high risk. Significant variables influencing addictive users were stress, self-efficacy, and the user's general characteristics including monthly spending money, sex, the hours of daily use, and the main method of use. CONCLUSION: It is concluded that such variables should be carefully considered in interventions for university students addicted to cell phone use.

OBJECTIVE: It is still the important subject that 3D visualizing of medical images to help patient diagnose. There were many challenges for fast 3D visualization but it has some limitations that volume rendering without high price's hardware and software. Some techniques through the web were suggested to construct high quality's 3D visualization even though it was an only poor personal computer. This technique could share the volume rendering board and diagnose 3D images together. However there are some problems to construct web based 3D visualization. These are network delay, optimized visualization and security etc. The purpose of this paper was to visualize and control the 3D medical image having a high quality on the web. METHODS: To construct this system, we used mainly three tools which were VolumePro1000 board, WMV9(Windows Media Video 9 Codec) and socket functions based on TCP(Transmission Control Protocol). VolumePro1000 board could calculate quickly heavy matrixes of 3D images using phong's shading and shear-warp factorization. WMV9 was able to compress efficiently live images and to apply image streaming technique. Socket functions based on TCP transmitted messages to control the 3D images. RESULTS: We developed 3D visualization system and evaluated about image qualities and transmission conditions of different compression rates on unfixed network condition. CONCLUSION: It was big advantages that WMV9 encoder could decode automatically in many platforms(desk top, PDA, notebook, cellular phone, etc) without installing specific decoding programs if they only have Windows Media player. We expect 3D visualization system to be utilized various biomedical fields such as IIGS(Interactive Image Guided Surgery), CAD(Computer Aided Diagnosis) and Tele-medicine technologies.

BACKGROUND AND OBJECTIVES: For the hearing-impaired population, quality of sound when listening to speech on mobile phone is often dissatisfactory. Even with a turning up the volume, they feel mobile speech unclear and desire the mobile sounds to be amplified as suited for the hearing characteristics. The purpose of this study was to estimate the appropriateness of NAL-NL1 fitting formula for the hearing-impaired mobile communication. MATERIALS AND METHODS: NAL-NL1 and a modified fitting formula (M-formula) were applied for sound amplification in consideration of individual hearing loss. Amplified speech material was presented for a word-recognition score (WRS) test in each subject. To simulate actual mobile phone sound, all speech material was filtered in 8 kHz low-pass filter and presented through a mobile phone to the subjects. Speech material was categorized into a speech-without-noise group and noisy speech group. RESULTS: Amplified sound with NAL-NL1 formula had a slightly better WRS than amplified speech with M-formula in speech-without-noise environments. However, in the noisy speech group, M-formula showed better WRS than NAL-NL1. CONCLUSIONS: For a good speech-perception in mobile phones, more high-frequency speech components need to be provided, especially for noisy environments. This study showed the possibility that specified fitting strategies may be applied for mobile phones to improve hearing in various environments, as with hearing aids.

The remote surveillance system based on the wireless home sensor network, wireless internet connection, and the portable, hand-held device has been designed for the patron to get the emergency alarm for immediate care for the Dementia aged, when the patron is not at home. It consists of transmitting server and the receiving terminal. The transmitting server gathers the information through bluetooth connection regarding to environment threatening the safety of the Dementia aged from five sensors, including fire, gas, conductivity, photo, and motion sensors, and cameras up to the number of 16, fixated within home. It also determines the emergency situation automatically from sensors' environmental condition and the motion detected from the camera output targeted to the aged people, and sends the alarm message with the picture taken from home to the patrol for comprehending the emergency situation remotely. Either the PDA or the cellular phone is used as the receiving terminal device through wireless connectivity without the location limitation for the patrol. The functional evaluation via the implemented prototype system has been performed to initially demonstrate the efficacy, the usefulness, and ease to operate for later use for either solitarily living old people or nursery schools and infantile shelters.

OBJECTIVES: We report a case of n-hexane-induced occupational peripheral polyneuropathy. The patient had been cleaning mobile phone cases using n-hexane for 3 years without proper protection in the workplace. Method : Physical examinations, detailed history taking, laboratory studies and electrophysiological study were done. The n-hexane concentration in the ambient air of the workplace was analysed. RESULTS: The findings of the electrophysiological study revealed that the worker's neurologic symptoms were due to peripheral polyneuropathy. The average n-hexane concentration in the ambient air sampled at the workplace for 59 minutes was 1411.24ppm, from which the 8 hour time-weighted-average(TWA) was estimated as 882ppm. Because other alternative causes for peripheral polyneuropathy were ruled out by laboratory findings and detailed history taking, this TWA level strongly suggested that the disease was caused by n-hexane exposure. Conclusion : Although the neuro-toxicity of n-hexane is relatively well known, many problems have been identified in the management of this toxic material in terms of preventing toxic diseases in the workplace. We expect that this case will help in the planning of health management strategies for using n-hexane in the workplace.
